Summary: Predicted to enable epidermal growth factor receptor binding activity; identical protein binding activity; and immunoglobulin binding activity. Involved in positive regulation of calcium ion import across plasma membrane. Acts upstream of or within response to bacterium. Located in external side of plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
